Problem fixed. This was basically an eclipse glitch, you have to include the external jars apriori as you create a project.

Personally, I'd like to see better comments more than better formatting. Two other points: First, we run code through a beautifier here so what you get out of source control will not necessarily be formatted like what you put into source control. E.g. the tool puts args on multiple lines like the Windows coding style. Works fine I think. Second, I've worked on lots of projects and the occassions for multiple people to touch the same source are alot less than imagined. Maybe two and possibly three people will ever change a block of code. The two cases I've seen are persons leaves and newbie takes over. Formatting can help because the task of reading and understanding the code is daunting. Other case is fixing some bug. IME, stupid variable names and plain poor coding are MUCH harder to fix than weird formatting. To me, individual formatting is like an artists' style and certainly we all know enough about compilers to realise it is syntactically the same. Maybe code formatting bothers other people more than me. So, my opinion is good coders can read code and understand it. Comments are more important than a particular fomatting. Modern tools that match braces and check syntax and flag errors dynamically make coding standards more of a business decision than engineering decision. As engineers and scientists we need to focus on real problems. That said, it is nice to be able to glance at Linux source and know something is a macro but I find following the links to the declaration more useful in any language because then you are 100% accurate. Oh yeah, WebLogic WorkShop only follows to the definition as of SP3! C'mon BEA! Even Eclipse is better at this!

And, since "manager " != "manager", your call to containsKey returns false.

It's a shortcut to String's Class object. Same result as Class.forName("java.lang.String"). And what do you mean ".this"? "this" is a keyword which is a reference to an instance of the class you're coding.

When a user presses search, a method collects the inputs and forwards them to a controllers search(Object criteria) method. So it may get a String[] or perhaps a single String or maybe an Object[] with Boolean and String etc. Each view has its own controller so the search method is tailored to that view, but it is being called via an interface method search(Object criteria) Is there a better way to design this? Or if this is broadly okay what is best practise to implement it properly, constants etc...
